Answer: 4.675×10^-6 m
Explanation: this is a question under the pattern gotten from an interference experiment.
The formulae below defines the experiment given
y = Rmλ/d
Where y = distance between the center fringe and any other fringe in the pattern = 8cm = 0.08m
m = position of fringe = 1 ( this is because we have only one central band)
λ = wavelength of light used for experiment = 680nm = 6.8×10^-7m
d = width of slit =?
R = distance between slits and screen = 5.5 cm = 0.055m
By substituting the parameters, we have that
0.08 = 0.055 × 1 × 6.8×10^-7/d
By cross multiplying, we have that
0.08 × d = 0.055 × 1 × 6.8×10^-7
d = 0.055 × 1 × 6.8×10^-7/ 0.08
d = 3.74 × 10^-7/ 0.08
d = 46.75×10^-7
d = 4.675×10^-6 m
Answer:
Explanation:
Faraday’s constant can be used to convert the charge (Q) into moles of electrons (n). The charge is the current (I) multiplied by the time
Q = I × t = n × F
Where
Q is charge
I is current = 0.2A
t is time = ?
n is number of mole
F is Faraday constant = 96500C/s
Mass of Au = 0.4 g = 0.0004kg
Molar mass of Au = 197 g/mol
Malar mass = mass / mole
n = 0.4 / 197
n = 2.03× 10^-3 mol
n = 0.00203 mol
t = n × F / I
t = 0.00203 × 96500 / 0.2
t = 979.7 seconds
t = 16.32 minutes.
The technical name was kinda given in the question, and I'm guessing that's what they want: Dispersion. It refers to the phenomenon of different frequencies traveling at different speeds through a medium. This is due to the fact that the relative electric permittivity is a complex quantity that is a function of frequency. The relative electric permittivity,
, is related to the speed of the wave in the medium by the relation:
Since this speed is a function of permittivity, and permittivity is a function of frequency, speed is a function of frequency.
Probably more info than you needed....
my bad i clicked the wrong question to do sorry i wish i could help but im dumb lol
